There was no doubt of it. Nelia had been there, but no one had happened to think to tell Carline about it. She had landed in a pretty shanty-boat, the wharf-master said, and had pulled out just before a river man in a brick-red cabin-boat of small size had left the eddy. The river man had dropped in just behind her, and, according to the wharf-master: "I shore kept my eyes on that man, for he was a riveh rat!" The thought was sickening to Carline. His wife floating down the river with a river rat close behind presented but two explanations: she was being followed for crime, or the two were just flirting on the river, together. He bought a pretty 28-foot motorboat, 22-inch draft with a 7-foot beam and a raised deck cabin. Having stocked up with supplies, he started down the Ohio to find his woman. He could not tell what his intention was, not even to himself; his mind, long weakened and depraved by liquor, lacked clarity of thought and distinctiveness of purpose. One hour he raged with anger, and murder blackened his heart; another minute, his shattered nerves left him in a panic of fears and remorse, and he hoped for nothing better than to beg his wife and sweetheart for forgiveness. At all times dread of what he might find at the end of the trail tormented him from terror to despair. His anguish overcame all his other sensations. It even overcame his lust for liquor. He grew sturdier under his affliction, so that when he arrived at Cairo, and swung his craft smartly up to the wharf-boat, his eyes were clear and his skin was honestly coloured by sunshine and pure winds. Here fortune favoured him with more news of his wife. The engineer of the Cairo-Missouri ferryboat had seen a young and pretty woman moored at the bank some distance from the landing. She had remained there upward of a week, having no visitors, and making daily visits over the levee into the little city. "One day she stood there, I bet half an hour, looking back, like she was waiting," the engineer said. "I seen her onto the levee top. Then she come down, jumped aboard with her lines, an' pulled out to go on trippin' down. I wondered then wouldn't some man be following of her." When Carline passed below the sandbar point, at which the Ohio and Mississippi mingle their waters, and the human flotsam from ten thousand towns is caught by swirling eddies, he found himself subdued by a shadow that fell athwart his course, dulling the fire of his own spirit with a doubt and an awe which he had never before known.
